BN_mod_inverse(3) OpenSSL BN_mod_inverse(3) NAME BN_mod_inverse - compute inverse modulo n LIBRARY libcrypto, -lcrypto SYNOPSIS #include <openssl/bn.h> BIGNUM *BN_mod_inverse(BIGNUM *r, BIGNUM *a, const BIGNUM *n, BN_CTX *ctx); DESCRIPTION BN_mod_inverse() computes the inverse of a modulo n places the result in r ("(a*r)%n==1"). If r is NULL, a new BIGNUM is created. ctx is a previously allocated BN_CTX used for temporary variables. r may be the same BIGNUM as a or n. RETURN VALUES BN_mod_inverse() returns the BIGNUM containing the inverse, and NULL on error. The error codes can be obtained by ERR_get_error(3).
